[GRASSLIST:6799] improved thematic mapper

[Michael Barton]

I just committed a set of updates to the thematic mapper, d.vect.thematic,
and posted it on my website.

There are several new options.

1. You can update the GRASSRGB column of a vector file with the thematic
colors. Thanks to Jachym Cepicky for this new feature.

2. You can now have a graphic legend (with either graduated colors or
graduated icons) drawn to the display monitor of your choice. Thanks to
Hamish for updating d.graph to make this possible. **Note: this only work
correctly for graduated colors with the new version of d.graph that Hamish
Bowman just committed to the CVS**.

3. You can create a custom color gradient by specifying start and end colors
as r:g:b triplets. Thanks to Markus for help with this.

4. The table connected to a vector map is automatically recognized,
regardless of its name. Thanks to Martin Landa for this.

Enjoy mapping!
Michael
